walletlink.social
Registry code: 329f9e1cb905f6fc
This server answers two questions about an Ethereum address: which social accounts its owner published, and which addresses a given X handle or Farcaster account is attested to. Balances, transfers and prices are a block explorer’s job.
An identity is attested when the wallet owner published the link themselves: a Farcaster verification, an onchain ENS record, an attested-social sign-in, or a manually verified record. Anything else is correlated, and labeled so. Nothing is inferred from a display name or a bio.

- Is walletlink.social live?
- Yes — it answered the hub's last check (checked 44m ago). It answered 99% of checks over the last 30 days.
- Is walletlink.social free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does walletlink.social have?
- 8 tools: walletlink_job_status, walletlink_wallets_by_x_handle, walletlink_wallets_by_farcaster_username, walletlink_account_balance, walletlink_index_coverage, walletlink_resolve_wallets, walletlink_submit_job, walletlink_estimate_list.
- Is walletlink.social safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
walletlink_job_status reads auth-required 11h ago
Progress and results for a job submitted with walletlink_submit_job. While the job runs it reports processed counts; on completion it reports the resolved records and what was billed. COST: free on both meters, so a drained key can still collect results it already paid for. A field that is absent was not measured. Absent is not false: a missing reachability means the handle was not checked, never that nobody is behind it. Only jobs submitted by this account are visible; any other id answers not found.

Find the wallets in the index attested to an X account. The reverse of resolving an address. Only wallets whose recorded sources are all attested come back, so a wallet whose attested link sits beside a correlated source is left out; resolving that address still shows it, labeled. Needs a key that belongs to an account: a key bought with USDC alone gets ACCOUNT_REQUIRED. COST: one match credit per wallet returned, and a page holds up to 100. A handle nobody holds returns an empty list and is free. The free allowance is 100 matches per 30 days, so a single widely held handle can spend all of it in one call. Check the balance first with walletlink_account_balance if that matters. A retried call bills its returned wallets again. Results are ordered by Farcaster follower count, highest first. When more_pages is true, pass next_cursor back to continue.

Find the wallets in the index attested to a Farcaster account. Only wallets whose recorded sources are all attested come back, so a wallet whose Farcaster verification sits beside a correlated source is left out; resolving that address still shows it, labeled. Needs a key that belongs to an account: a key bought with USDC alone gets ACCOUNT_REQUIRED. COST: one match credit per wallet returned, and a page holds up to 100. A username nobody holds returns an empty list and is free. A retried call bills its returned wallets again. Pass the username whole, including any .eth suffix: an ENS name attached to a Farcaster account is a large share of the index, and stripping the suffix will find nothing. Results are ordered by follower count, highest first.

How many match credits the configured key has left, and how much of the request allowance it has used. COST: free on both meters. Call it before a reverse lookup, which can spend up to 100 credits in one go. matches_available is the meter that stops a metered call: at zero, the resolve and reverse tools refuse, while this tool and the coverage tool keep answering, so a drained key can always read its own meter. rate_limit_units_used is a separate count of requests and is not a credit figure. unmetered is true on an account that is never debited. Its matches_available is null because it has no balance to report, not because the balance is zero.
{ "type": "object", "properties": {} }arguments 4 lineswalletlink_index_coverage reads auth-required 11h ago
How much of the index carries each identity type. Use it to judge whether a lookup is worth making before making it. COST: free on both meters. It resolves no wallet and consumes no rate limit. A key whose balance is zero can still read the free endpoints; the balance and coverage reads keep answering at zero, and only a call that could bill refuses with NO_CREDITS. addresses_with_an_identity over addresses_checked is the coverage rate. The second number is larger because it counts addresses we have looked at and found bare. The counts are refreshed daily rather than counted live; as_of says when they were taken, and asking twice in a day returns the same numbers.
{ "type": "object", "properties": {} }arguments 4 lineswalletlink_resolve_wallets reads auth-required never probed
Resolve one or more Ethereum addresses to the social identities attached to them: X handle, Farcaster account, ENS name, Lens profile, GitHub account. COST: one match credit per address that resolves to an X handle or a Farcaster account. An address that resolves to nothing is free, and so is one carrying only an ENS name, a Lens profile or a GitHub account. Up to 50 addresses per call on the default plan; a live Scale pack raises the ceiling to 200 and Index to 1000, and the API refuses over YOUR ceiling with BATCH_SIZE_EXCEEDED naming it. A batch call spends one request-unit per address of the per-minute window, and a full batch fills most of a minute on every plan: the default plan gives 60 units per minute and 50-address batches, and a live Scale or Index pack raises both. Pace multi-batch runs a minute apart and read the reset time from the quota. Each identity reports whether the address owner attested it rather than it being correlated by a third party, and each X handle reports whether it still reaches anyone: a handle can be attested and suspended, or freed and since taken by a stranger. Send every address you need in one call. Duplicates are removed before you are charged, but each copy still costs throughput. A retried call bills again: duplicates are removed inside one call, never across calls, and a tool call cannot carry an idempotency key. Before resending a call that may have gone through, read the balance instead of guessing.

Submit a list of addresses as a background job. A job runs a deeper scan than the resolve tool: an address the index has not checked, or holds only stale answers for, is resolved against live sources, so a job can find identities the resolve tool reports as never seen. Use it for lists larger than one resolve call, or when misses are worth re-checking. COST: billed on matches exactly like resolving, when the job completes: one match credit per address that resolved to an X handle or a Farcaster account, misses free. One job may be active per account at a time; a second submission is refused until the first finishes, and the refusal names the active job id. A submission is capped at 10 times the match balance, so the worst case is bounded by what the account already holds. Submitting itself spends one request-unit of the rate window. The submission returns a job id. Poll walletlink_job_status for progress and, on completion, the results. A job that fails is never billed. Resubmitting the same list after a job completes runs the whole job again and bills its matches again.

The ceiling is the balance-derived cap, not a fixed number; a list over the cap is refused with the cap named." } } }arguments 18 lineswalletlink_estimate_list reads auth-required 4h ago
A dry run over a list of addresses: how many are in the index, how many were checked and found bare, how many have never been seen, and the band a resolve would bill inside. Counts only, no identities. Use it to decide whether a list is worth resolving, and which tool to spend on. COST: free on the match meter, always, even at zero balance. It weighs the rate window exactly like resolving the same list (one request-unit per address), so it previews a batch at the batch’s own pace. Minimum 10 distinct addresses, because the counts are aggregates by design; the ceiling is your plan’s batch ceiling. Reading the band: low is exact for resolving this list now (the addresses already holding an X handle or a Farcaster account). high adds never-checked addresses at the measured overall rate; a background job resolves those against live sources, a plain resolve does not. Match rates differ several-fold by chain; the coverage tool and /v1/stats carry the measured per-chain table.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
